In ShortA pink and blue color scheme, white tile floors and hacienda-like arched windows combine for a subtle Southwestern motif at this fast-food chain. Founded in Southern California in 1962 by Glen Bell (who invented the pre-fab hard taco shell), this casual order-at-the-counter Mexican restaurant features classics like tacos, nachos, quesadillas and burritos. In recent years, menu offerings have expanded to include specialty items like gorditas, chalupas and cinnamon twists.
